COUPLING FOR OIL-WELLS.

Specification of Letters Patent.

Application filed August as, 1914. Serial No. 859,079..

To all whom it may concern Be it known that I, ALBERT B. SOLINGER, a citizen of the United States, residing at Sackett, in the county of Elk and State of Pennsylvania, have invented certain new and useful Improvements in Couplings for Oil- Wells; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to new and useful" improvements in coupling apparatus for oil and other wells and resides in the provision of a simple and effective coupling member that will serve to couple the stand pipe with the well tubing of a well and suspend A the tubing from the well casing at the upper part of the well in such manner that the I go tubing will not become detached from the "coupling member from shocks or Jars or from heat caused by fire.

Another object is to provide a couplingmember of the character described that may be easily and readily put into position and which is simple as to construction and inexpensive to manufacture.

Another ob ect is to gene-rally improve coupling members of the character described W so as to'render them more practical, rellable and efiicient in operation and more durable and commercially desirable.

The above and additional objects are accomplished by such means as are illustrated 85 in the accompanying drawings, described in the following specification and then more particularly pointed out in the claims.

With reference to the drawings, wherein I have illustrated the preferred embodiment of my invention as it is reduced to practice,

and throughout the several views of which similar reference numerals designate corresponding parts.

Figure 1 is a detail side elevation of the coupling member removed from the casing.

Fig. 2 is a fragmentary vertical sectional view taken through a well showing the-coupling members in .position.

Referring to the drawings by characters of reference, the numeral 1 designates as an entirety the platform of the well, 2 the well casingmounted on the platform, and 3 a collar threaded upon the upper end of the casing 2 exteriorly thereof.

85 My improved coupling member designated 4 as an entirety serves to connect the well tubing 5 with a vertical stand pipe 6. A discharge pipe 7 is connected with the stand pipe 6 and extends outwardly therefrom at right angles thereto.

My improved coupling 4 comprises a tubular body portion 8 that is formed intermediate its endswith an annular flange 9. The flange 9 is provided upon its lower face and the periphery thereof with a depending marginal flange 10 that is designed to seat within an annular groove 11 formed in the upper face of a supporting ring 12. The

supporting ring 12 is positioned within a recess 13 formed in the upper part of the collar 3 on the upper end of the casing 2 and rests upon the upper end of the casing 2 as well as the collar 3. The supporting ring 12 snugly fits the tubularxbody 8-of the coupling member 4. The ends of the coupling member 4 interiorly thereof are screw threaded as at 14.- and receive the externally screw threaded ends of the tubing and stand pipes 5 and 6 respectively. The usual plunger rod 15 is mounted within the tubing, coupling member. and stand pipes.

With my improved couplingmember it will be readily seen that the stand. pipe and tubing may be coupled'in such manner that derangement of the tubing relative to the coupling member and stand pipe is preyented. The interior connection of the tubing with the coupling member insures the holding of the tubing in case of fire since the heat will not affect the threads so as to cause the tubing, to drop from the coupling member.

The device may be readily assembled and as easily disassembled for shipment or storage but serves principally to'expedite the setting up of well structures.

In practice, I have found that the form of my invention, illustrated in the drawings Patented May a, 1915.

flange formed intermediate the ends of the body portion, a depending marginal flange on the under face of said annular flange and a ring having an annular groove in its upper I face to be mounted upon the upper part of the Well structure and receiving the depending flange in the groove'thereof.

2. The combination with a well casing, I

stand pipe and Well tubing of a coupling member for the tubing and stand pipe consisting of a tubular body portion having internal screw threads at its ends receiving the adjacent ends of the stand pipe and Well tubing, an annular flange formed integral Withthe coupling member intermediate the 15 ALBERT B.
